Bug 1493785

Description of problem:
The way of creating Service Orders with multiple service requests described in documentation [1] fails with "no implicit conversion of Symbol into Integer" error.
[1] http://manageiq.org/docs/reference/latest/api/reference/service_orders#creating-service-orders

That's the only way of creating a shopping cart described in the documentation.

This problem can be workarounded by creating and empty cart:
POST /api/service_orders
{ "action": "create", "name": "cart" }
and then adding service requests using the "add" action.

}
